Abstract
Description
Technischer Bereichtechnical Area
Die vorliegende Erfindung bezieht sich auf eine Synchronisiervorrichtung nach dem Oberbegriff des Patentanspruchs 1.The The present invention relates to a synchronizer according to the preamble of claim 1.
Stand der TechnikState of technology
Bei Schwerfahrzeugen wie beispielsweise Lastwagen ist es bekannt, dass mit dem Hauptgetriebe des Fahrzeugs ein Zusatzgetriebe verbunden wird, um die Anzahl der möglichen Übersetzungsverhältnisse der Zahnräder zu verdoppeln. Solch ein Zusatzgetriebe umfasst gewöhnlich ein Planetengetriebe, das es ermöglicht, zwischen einem niedrigen und einem hohen Übersetzungsbereich zu wechseln. Ein Gangwechsel im Planetengetriebe wird im niedrigen Übersetzungsbereich benutzt aber nicht im hohen Übersetzungsbereich. Eine bekannte Vorgehensweise, den Übergang zwischen hohen und niedrigen Übersetzungsverhältnissen zu erleichtern, besteht darin, dass solche Planetengetriebe mit Synchronisieranordnungen vorgesehen werden.at Heavy vehicles such as trucks it is known that is connected to the main transmission of the vehicle, an additional transmission, by the number of possible gear ratios the gears to double. Such an auxiliary transmission usually includes a Planetary gear that makes it possible to switch between a low and a high translation range. A gear change in the planetary gear is in the low gear range but does not use in the high translation range. A well-known procedure, the transition between high and low gear ratios To facilitate, is that such planetary gear with Synchronization arrangements are provided.
Es hat sich herausgestellt, dass es unter dem Gesichtspunkt der Lastverteilung vorteilhaft ist, den Zahnkranz des Planetengetriebes als Verbindungshülse zu verwenden, die durch axiale Bewegung in Eingriff mit Kupplungsringen auf beiden Seiten des Planetenrades gebracht werden kann. Eine wirksame Handhabung der Synchronisierringe zu erreichen, die mit den Kupplungsringen zusammenwirken und für die Synchronisierung erforderlich sind, hat sich jedoch als problematisch erwiesen, wenn der Zahnkranz in verschiedenen Richtungen in Fällen bewegt wird, in denen die Gesamtlänge des Planetengetriebes kurz ist.It has been found to be from the point of view of load distribution advantageous to use the ring gear of the planetary gear as a connecting sleeve, by axial movement in engagement with coupling rings on both Sides of the planetary gear can be brought. An effective handling to reach the synchronizer rings with the coupling rings interact and for However, synchronization is required has been problematic proven when the sprocket moves in different directions in cases in which the total length of the planetary gear is short.

Aufgabe der ErfindungObject of the invention
Aufgabe der Erfindung ist es, bei Aufrechterhaltung einer guten Wirkungsweise eine vereinfachte Synchronisiervorrichtung vorzusehen.task The invention is, while maintaining a good mode of action to provide a simplified synchronizing device.
Beschreibung der Erfindungdescription the invention
Die Aufgabe der Erfindung wird mittels einer Anordnung mit den im Patentanspruch 1 angegebenen Merkmalen gelöst.The The object of the invention is by means of an arrangement with the in claim 1 specified characteristics solved.
Den Zahnkranz mit nur zwei ringförmigen Sperrvorrichtungen zu versehen, die sich in inneren Nuten im Zahnkranz festhalten, vereinfacht sowohl die Bearbeitung wie den Zusammenbau. Die Sperrvorrichtungen selbst sind ebenfalls einfach gestaltet. Dass die Sperrvorrichtungen direkt in den Zahnkranz eingebaut sind, bedeutet auch, dass kein zusätzlicher Raum in axialer oder radialer Richtung erforderlich ist. Dies ermöglicht eine raumsparende Bauweise des Planetengetriebes.The Sprocket with only two annular locking devices to be provided, which hold in internal grooves in the sprocket, simplifies both machining and assembly. The locking devices themselves are also simply designed. That the locking devices built directly into the sprocket also means that no additional Space in the axial or radial direction is required. This allows a Space-saving design of the planetary gear.
Weitere Merkmale und Vorteile der Erfindung werden im Folgenden in der Beschreibung und den Patentansprüchen angegeben.Further Features and advantages of the invention will become apparent in the description and the claims specified.
Die Erfindung wird nun in weiteren Einzelheiten mit Bezug auf eine in den beigefügten Zeichnungen abgebildete Ausführungsform erläutert.The Invention will now be described in further detail with reference to a the attached Drawings illustrated embodiment explained.

Es lässt sich beispielsweise bei automatischen hydraulischen Getrieben verwenden, bei denen mehrere Planetengetriebe zusammengekuppelt sind.The described planetary gear can also be used in other contexts used as described herein. It can be, for example, at use automatic hydraulic transmissions in which several Planetary gear are coupled together.
Die Erfindung kann auch bei Synchronisiervorrichtungen der Bauart verwendet werden, bei der auf beiden Seiten des Planetengetriebes eine Vielzahl Synchronisierringe angeordnet ist. The The invention can also be used with synchronizing devices of the type be, at the on both sides of the planetary gear a variety Synchronizing rings is arranged.
